I have installed Cisco Packet Tracer 7.1.1 on Ubuntu 18.04. Every time I launch the application it closes and give me a message Segmentation fault (core dumped).
Using the gdb, I went to the installation directory /opt/pt/bin and I typed the following commands:



$gdb Packettracer
$gdb > run
$gdb > where


Which reports a problem with libpng and libcrypto.so.1.0.0



Warning: libpng warning: iCCP: known incorrect sRGB profile
Warning: libpng warning: iCCP: known incorrect sRGB profile

Thread 1 "PacketTracer7" received signal SIGSEGV, Segmentation fault.
0x00007ffff79f49a7 in CRYPTO_add_lock () from /usr/lib/x86_64-linux- gnu/libcrypto.so.1.0.0


How can i fix this?

  • Thank you for great debugging method, I can confirm this issue on clean installation of Ubuntu 18.04 LTS. If it is possible, please report bug to Cisco. We can not change anything on Ubuntu side, I think. But they can recompile their proprietary software to support Ubuntu 18.04 LTS. We can not downgrade libcrypto.so.1.0.0 because it is a part of libssl1.0.0 package, which has a lot of reverse-dependencies. As alternative you may try previous version of CPT. But CPT 7.1.1 works on 16.04 LTS (see my answer).

    It seems to be a problem in the PacketTracer implementation.



    I had the same issue here, but I solved the problem using the previous version of Packet Tracer (7.0).
    The Packet Tracer 7.0 is available at the Netacad portal.
